DAC Support?
Does it support DAC? I just found ADC but not DAC.
timer.rs
I see there's some unfinished timer code in timer.rs. Whats the status of that and could you give any pointers on what needs to be done to get it working?
Assorted Delay feedback
Besides the overflow MR, I also have some less concrete feedback:
At first when I tried the code sample you provided in martindisch/gd32vf103-demo#1, I ran into an error
error[E0432]: unresolved import `gd32vf103_hal::rcu::Strict`
--> src/main.rs:11:55
|
11 | ctimer::CoreTimer, delay::Delay, pac, prelude::*, rcu::Strict,
| ^^^^^^^^^^^ no `Strict` in `rcu`
But I quickly noticed that this is just because I was using the 0.0.2 version from crates.io which doesn't work with that yet (even though it's pretty recent). Using the latest from Git solved it for me. This is not really an issue, as it will be fixed when you publish the next version of your crate.
Another thing concerns the delay accuracy. Just like you, I don't have any equipment I can use to do exact measurements, but small inaccuracies aren't the issue here. On my device it seems more like it's off by a factor of 2. I adjusted the delay blinky example to use a 10000 ms delay and when timing by hand, the LED only ended up being toggled about every 20 seconds. I didn't read any documentation so am not confident enough to go ahead and issue a MR, but it seems to me like maybe the divide by 2 in delay.rs is wrong and should be 4 instead?

fn delay_ms(&mut self, ms: T) {
- let count: u32 = ms.into() * (self.clock_frequency.0 / 1000 / 2);

// todo: avoid using u64 values in this function
let tmp: u64 = self.ctimer.get_value();
let end = tmp + count as u64;At least on my device this fixed the problem and now I'm very close to the 10 seconds I set the delay for.
What toolchain are you using?
Hi, I've been working on building a toolchain for the gd32vf103 from these sources. I've encountered a number of issues along the way. In cb6ce40 you refer to a riscv64-unknown-elf toolchain, which matches what I'm trying to build. I was wondering where you got this toolchain. If you built it from source would you be able point me at the sources?
Thanks in advance, and for your embedded Rust work.
